Abstract
An apparatus has a computer receiving input signals indicative of fetal heart rate (“FHR”) and maternal uterine activity in a patient. The computer determines when each of FHR, baseline FHR variability, FHR accelerations, FHR decelerations, and maternal uterine activity exhibit a plurality of pre-defined non-reassuring characteristics. The computer receives inputs indicating the presence of maternal, obstetrical, and fetal risk factors, and determines at predetermined times during labor a present level of risk to the fetus which accounts for the total of the number of parameters that each exhibit the non-reassuring characteristics at predetermined points in time during labor and the number of risk factors present. An output display depicts in a single graphical interface information respecting the parameters and risk factors over time during labor. The graphical interface includes indicia for indicating the present level of fetal risk at the predetermined times during labor and signals the need for intervention.
